STANDARD CELL FOR MULTIPLE POWER SOURCES, STANDARD CELL LIBRARY FOR AUTOMATIC ARRANGEMENT AND WIRING, POWER SUPPLY WIRING METHOD, AND SEMICONDUCTOR INTEGRATED DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem that, when N wells of a standard cell for a single power source and a standard cell for a plurality of power sources come into contact with each other, the operating speed of the standard cell for the plurality of power sources varies, and the problem that when the N wells are arranged at an interval, tolerance to latch-up is lost since substrate contact is insufficient.;SOLUTION: The standard cell for the plurality of power sources is equipped with a 2nd power line 408 which is electrically separated from a 1st power line 401 in addition to the 1st power line 401 and N wells 404 are arranged at a distance from the entire circumferential border of the cells. Even when the cells are adjacent in a column or row direction, the N wells in the standard cell for the plurality of power sources can be separated from N wells of the cells which are adjacent in the column or row direction.;COPYRIGHT: (C)2004,JPO
